A)be no different.
B)double.
C)quadruple.
If the low-energy and high-energy fuels are burned in the same time, then compared to the POWER produced by combustion of the low-energy gasoline, the power produced by the combustion of the higher-energy gasoline should
D)be no different
E)double
F)quadruple

Question

Quizplus · Accepted Answer

The energy content of gasoline is directly proportional to the distance a car can travel per liter of gasoline. Doubling the energy content would double the distance traveled. The power produced by combustion is directly proportional to the energy content of the fuel. Doubling the energy content would double the power produced.
